Japanese wearable tech company Neurowear has developed a new concept for geotagging your mood. Using NeuroSky’s brain activity-measuring headset and a heart monitor, they determine your emotional state and tag your current location with an icon showing how you’re feeling. This creates a map of places that you found exciting, relaxing, or even frightening. This can be shared with friends to let them search by emotions if they’re looking for a place to suit their mood.

Neurowear has also developed a tail that communicates with the headset via Bluetooth, which they unveiled at this year’s Tokyo Games Show. ‘Shippo’ (which means ‘tail’ in Japanese) is a brain-controlled motorized tail that demonstrates the wearer’s current mood by wagging fast (concentrating/excited) or slow (relaxed).
